RHN Satellite Server Installation Program

Follow the instructions to run the RHN Satellite Server Installation Program:

1. Log into the machine as root.2. Insert the RHN Satellite Server CD containing the installation files or download the ISO image

from the RHN website.

3. Create a directory in /mnt to store the files with the command:mkdir /mnt/cdrom

4. If you are installing from CD and it is not mounted automatically, mount it using the command:mount /dev/cdrom /mnt/cdrom

5. If you are installing from download, mount the file from within the directory containing it using thecommand:

mount iso_filename /mnt/cdrom -o loop

6. The rest of the instructions assume it is mounted in /mnt/cdrom.7. Ensure the RHN Entitlement Certificate has been loaded onto the Satellite. It can be named

anything and located in any directory. The installation program will ask you for its contents or

location. Also, make sure your account has been granted the necessary entitlements to conduct

the installation. For instance, a new Satellite will require both a Management or Provisioning

entitlement for Red Hat Enterprise Linux AS and an RHN Satellite Server entitlement.

Warning

Users should note that the RHN Satellite Server Installation Program updates the kernel, aswell as all required packages.

8. Launch the RHN Satellite Server Installation Program as root with the command:/mnt/cdrom/install.sh

9. This script runs through the pre-installation process without user intervention. See Figure 1 Thistakes between 20 and 30 minutes.

Figure 2. Administrator Email Address

12.The Administrator Email Address page requires an email address to receive administrativecorrespondence. Ideally, this address serves multiple people in your organization to ensure

delivery. Keep in mind, this address will receive all mail generated by the Satellite, including

sometimes large quantities of error-related tracebacks. To stem this flow, consider establishingmail filters that capture messages with a subject of "RHN TRACEBACK from hostname".

Click Continue . The Database Configuration page appears for RHN Satellite Server with

Stand-Alone Database, while the Database Schema page appears for RHN Satellite Server with

Embedded Database.

Figure 3. Database Configuration

13.The Database Configuration page collects information required for the Satellite with Stand-Alone Database to connect to its database. If this is Satelllite with Embedded Database, skip to

the Database Schema page description. For Satellite with Stand-Alone Database, consult your

database administrator for the appropriate values. Then click Test DB Connection .

The Database Schema page appears.

14.No input is required on the Database Schema page other than your consent. Click Continue topopulate the database. This too can take a while. The Database Population page appears to

help you track progress.

Figure 5. Database Population

15.The Database Population page displays a link when population is complete.Click Configuration to continue. The RHN Configuration page appears.

Figure 6. RHN Configuration

16.The RHN Configuration page enables you to change the way the Satellite communicates withRed Hat Network. You may alter the Satellite's hostname, its parent RHN server (to connect to

another Satellite, for instance) and the location, or mountpoint of the package repository.

Typically, the defaults will do. If you intend to monitor systems with this Satellite, select both

the Enable monitoring backend and Enable monitoring scout checkboxes.

In addition, this page allows you to configure the Satellite to use an HTTP proxy server. To do

this, complete all associated fields. Note that references to protocol such as http:// or https://

should not be included in the HTTP proxy server field. Insert only the hostname and port in the

form hostname:port, such as my.corporate.gateway.example.com:3128 . When finished,

click Continue. The Monitoring Configuration page appears.

Figure 7. Monitoring Configuration

17.The Monitoring Configuration page captures email routing information used in monitoring. Thisis required only if you intend to receive alert notifications from probes. If you do, provide the mail

server (exchanger) and domain to be used. Note that sendmail must be configured to handle

email redirects of notifications. When finished, click Continue. The RHN Registration page

appears.

Figure 8. RHN Registration

18.The RHN Registration page enables you to register the Satellite with Red Hat Network, allowingit to get updates and software channel package data directly. To register the Satellite, ensure its

system profile name is correct (usually the hostname) and complete the RHN

Username and RHN Password fields with the account information provided by your sales

representative or established previously by you. This account must be entitled for RHN Satellite

Server.

To skip this step, such as for Satellites that will operate in disconnected mode, click eitherthe continue link or button. If you do not register the Satellite, the RHN Satellite

Synchronization Tool cannot be used to populate software channels. Contact your Red Hat

representative to obtain the packages and updates manually. When finished, clickContinue.

The RHN Satellite Entitlement Certificate page appears.

Figure 9. RHN Satellite Entitlement Certificate

19.The RHN Satellite Entitlement Certificate page gathers your RHN Entitlement Certificate eitherby obtaining its location or collecting its contents. To identify the certificate's path, click Browse ,

navigate to the file, and select it. To input its contents, open your certificate in a text editor, copy

all lines, and paste them directly into the large text field at the bottom. Red Hat recommends

using the file locator as it's less error prone. Click Validate Certificate to continue. If you receive

errors related to DNS, ensure your Satellite is configured correctly. The Satellite

Synchronization page appears next.

Figure 10. Satellite Synchronization

20.The Satellite Synchronization page allows you to initially populate your Satellite with softwarechannel metadata. This is possible during installation only if you chose to register your Satellite

with RHN. To synchronize, select the Perform Satellite Sync checkbox and click Continue .

After the installation, you will still need to populate the channels with packages. The SSL

Certificate page appears next.

21.The SSL Certificate page collects information necessary to create the Secure Sockets Layer(SSL) certificate used by the Satellite and its client machines. In addition, you may manage your

SSL infrastructure using the RHN SSL Maintenance Tool.

Create an SSL Certificate Authority (CA) password and complete the rest of the fields with your

and your organization's information. The CA Cert Common Name field may already be

populated with the name of the host machine. This may need to be altered if you're using multiple

RHN Servers in tandem.

Use the Expiration fields at the bottom to establish usage limits for the Certificate Authority and

the certificate. The public certificate will be placed in the /var/www/html/pub/directory on the

Satellite where it can be downloaded from and installed on all client systems. Once finished,

click Generate Cert . The Bootstrap Script page appears next.

Figure 11. SSL Certificate

22.The Bootstrap Script page allows you to create a script for redirecting client systems from thecentral RHN Servers to the Satellite. This script, to be placed in

the/var/www/html/pub/bootstrap/ directory of the Satellite, significantly reduces the effort

involved in reconfiguring all systems, which by default obtain packages from the central RHN

Servers. The required fields are prepopulated with values derived from previous installation steps.

Ensure this information is accurate.

Checkboxes offer options for including built-in security SSL and GNU Privacy Guard (GPG)

features, both of which are advised. In addition, you may enable remote command acceptance

and remote configuration management of the systems to be bootstrapped here. Both features are

useful for completing client configuration. Finally, if you are using an HTTP proxy server,
